Where  Gravity  Does  the  Trucking 

No  wasted  time  here.  Lamson  Gravity  Conveyors  carry  these  electric-light  bulbs  in  trays  of 
fifty  each  from  the  etching  machines  to  the  washing  tank  in  the 
Westinghouse  Lamp  Works,  New  York 


T  is  easy  to  supervise  an  organization  of  a  hundred 
men  in  an  office  or  manufacturing  department  who  are 
doing  certain  specified  tasks,  but  have  you  tried  to 
control  five  porters  who  are  all  over  the  plant  and  doing 
different  work  every  hour?  Then  you  know  how  hard 
it  is  to  get  maximum  production  from  every  department 
if  you  rely  on  these  porters  to  carry  the  materials  and  parts  where  they 
should  go. 

Does  This  Ever  Happen  in  Your  Plant? 

The  forwarders  mean  well,  but  they  can’t  be  everywhere  at  once. 
While  they  are  out  in  the  yard  unloading  a  car  of  raw  stock,  a  dozen 
highly  paid  workmen  run  out  of  materials  in  the  shop.  These  skilled 
men  have  to  leave  their  machines  idle  while  they  truck  the  needed 
material  —  they  stop  their  productive  work  for  a  lumper’s  job. 

You  can’t  expect  the  porters  to  learn  the  problems  of  your  business 
and  judge  just  what  work  is  most  urgently  needed.  They  are  hired  to 
carry  materials  and  parts,  not  to  make  decisions. 

You  can  give  them  the  most  explicit  instructions,  but  when  a  lumper 
passes  a  foreman  or  workman  who  is  clamoring  for  more  stock,  you 
can’t  blame  him  if  he  tries  to  help  out  and  forgets  your  orders  for  the 
moment. 

Look  over  your  floors.  Are  they  clogged  with  parts  and  stock  waiting 
to  be  moved  by  the  forwarders?  This  is  one  of  the  big  reasons  why 
production  does  not  increase;  why  manufacturing  costs  are  going  up; 
why  the  “stock  in  process”  account  is  so  large;  why  it  takes  so  long 
to  complete  a  shipment  after  receiving  the  order;  why  it  is  so  hard  to 
rush  out  emergency  orders  without  seriously  interfering  with  the  rest  of 
the  work.  And  this  is  one  of  the  big  reasons  for  the  difficulty  of  getting 
out  the  work  on  time  in  the  warehouse,  freight  shed,  on  the  construction 
job ;  in  fact,  wherever  materials  and  products  are  moved. 

You  have  studied  the  processes  and  machines  connected  with  your

efficiency,  but  have  you 
given  the  same  careful 
study  to  a  system  for 
transporting  materials 
most  efficiently  between 
operations  and  for  carry¬

production  are  not  due 
to  poor  machinery;  the 
workmen  are  not  to  blame ;  it  is  not  up  to  the  porters,  they  are  doing  the 
best  they  know  how.  The  trouble  is  simply  that  the  method  of  handling 
the  product  is  out  of  date.  But  there  is  a  new  way  of  handling  that  will 
do  away  with  all  these  difficulties. 


Clearing  the  Way  for  Production 

Conveyors  solve  your  handling  problem.  They  clear  the  way  for 
production  —  they  put  an  end  to  the  confusion  and  delays  that  interfere 
with  the  main  business  of  your  plant. 

You  don’t  have  to  worry  about  the  movement  of  materials,  but 
can  give  your  entire  attention  to  your  more  important  problems  of 
production. 

You  can  plan  out  the  most  economical  routing  of  materials  once 
for  all  —  the  conveyors  make  certain  that  this  routing  is  exactly  fol¬ 
lowed.  They  carry  all  parts  and  materials  quickly,  automatically,  and 

safely  where  they  should 
go. 

Portable  conveyors

BY  GRAVITY 


As  Flexible  as  a  Railroad  Track 

With  switches  and  curves,  Lamson  Gravity  Conveyors  can  be  run  between  machines,  through 
partitions,  around  columns  and  obstructions,  —  they  carry  products  wherever  wanted.  A  pull 
on  the  handle  of  the  switch  shown  in  the  picture  diverts  packages  to  either  line 


building  materials,  and  wherever  products  are  moved.  Stock  in  process 
is  kept  down  to  a  minimum,  as  it  is  always  on  the  move  from  receiving 
room  to  shipping  platform.  There  is  no  accumulation  of  partly  finished 
material  between  machines  and  in  the  aisles. 

Production  from  a  given  floor  area  is  increased  often  over  fifty 
per  cent.  More  machines  can  be  installed  on  floors  that  are  kept 
clean  of  stock  and  moving  trucks,  while  the  machinery  is  run  to 
capacity  all  day  long  when  conveyors  keep  the  workmen  supplied 
with  materials. 

If  your  plant  is  badly  arranged,  through  additions  built  to  accommo¬ 
date  an  expanding  business,  you  do  not  have  to  rebuild  to  secure  manufac¬ 
turing  efficiency  —  simply  link  up  your  scattered  buildings  with  conveyors. 
Your  plant  is  again  united  into  a  single  working  unit  —  you  obtain  the 
efficiency  of  a  new  plant  at  a  small  fraction  of  the  cost. 

Conveyors  protect  materials  and  products  from  bruising,  scratching, 
and  other  damage,  which  often  results  in  considerable  loss  where  finished

articles  are  trucked  by  hand.  They  convey  them  “  Indian  file,”  safe  and 
free  from  damage. 

Modern  machinery  and  processes  are  essential,  but  conveyors  are  just 
as  important,  as  without  them  the  best  equipment  cannot  produce  the 
results  expected.  The  first  cost  of  conveyors  is  soon  absorbed  by  the 
savings  that  continually  appear  on  the  balance  sheet.

Our  conveyor  bearings  are  designed  to  carry  heavy  loads  and  give  long  service.  All  wearing 
parts  are  case-hardened  and  are  made  extra  big  and  strong  to  stand  the  hardest  kind  of  use. 
At  the  same  time  our  bearings  are  so  accurately  made  that  they  will  carry  loads  with  less 
grade  than  any  other  conveyor.  Every  bearing  is  easily  removable  for  cleaning. 

The  roll  and  heads  are  welded  together,  making  them  practically  one  piece  of  metal.  The 
large  diameter  spindle  keeps  the  rolls  in  perfect  and  exact  alignment.

M)  -  CONVEYING  BY  GRAVITY 


THE  LAMSON  GRAVITY  CONVEYOR 

THE  Lamson  Gravity  Conveyor  is  the  “Industrial  Roller-Coaster” 
for  carrying  all  kinds  of  products  in  every  business.  It  oper¬ 
ates  for  practically  nothing  as  it  uses  the  free  power  of  gravity, 
which  is  on  the  job  twenty-fours  hours  a  day  —  365  days  in  the 
year.  Its  construction  is  simple  —  it  consists  of  a  series  of  lively  rollers 
carried  in  a  sturdy  angle  iron  frame.  When  the  conveyor  is  set  at 
a  slight  inclination,  packages  or  products  placed  upon  its  rollers  move 
along  of  their  own  free  will,  without  any  care  or  attention  whatsoever. 

What  It  Will  Carry 

Boxes,  barrels,  rolls  of  paper,  castings,  brick  and  tile,  lumber,  and 
all  products  having  at  least  one  flat  surface  are  carried  directly  on  the 
conveyor.  Small  parts  are  carried  in  tote  boxes,  while  bags  of  cement 
and  grain,  rolls  of  cloth  and  products  of  irregular  shape,  are  carried  in 
simple  trays  or  containers,  or  on  pallets. 


“Shipments  for  Points  South  Take  the  Right-Hand  Chute” 

How  to  separate  the  thousands  of  packages  for  ready  shipment  to  various  states  was  a 
problem  with  Sears  Roebuck  &  Company  in  their  Seattle  Warehouse.  It  was  answered  by 

Lamson  Gravity  Conveyors  and  Chutes 

[9] 


CONVEYING  BY  GRAVITY 


Move  This  Conveyor  Wherever  You  Want  It 
This  portable  conveyor  is  useful  where  packages  or  boxes  are  stored,  as  it  can  be  moved 
wherever  it  is  wanted.  It  is  equally  valuable  for  piling  incoming  packages  or  starting  outgoing 

packages  on  their  way 


The  Lamson  Roller 


The  success  of  the  gravity  conveyor  depends  on  the  roller.  The  roller 
in  our  conveyor  is  built  of  steel  throughout,  with  the  same  care  and 
attention  that  goes  into  the  construction  of  other  high-grade  machinery. 

It  runs  on  large,  accurately  made,  self-contained  ball  bearings,  with 
hardened  ball  races  and  cones,  like  the  bearings  in  the  best  automobiles. 

The  rollers  and  bearings  are  simple  and  easy  to  get  at.  The  spindle  is 
released  by  simply  removing  one  split  pin— the  roll  head  and  self-contained 
bearing  are  then  readily  accessible. 

The  Frame 


The  Lamson  Frame  is  like  a  steel  bridge, 
—  light,  but  scientifically  braced  to  with¬ 
stand  deflection  and  side-sway.  The  side 
angles  are  not  weakened  by  large  slots  or 
bearing  holes,  but  have  maximum  strength 
where  strength  is  needed. 

Supports 


„  ,  ,  , ,  Adjustable  steel  supports  hold  the  con- 

Our  strong  conveyor  is  made  doubly 

strong  by  this  sturdy  cross  brace  veyor  at  a  convenient  height  in  shipping 


[10] 


Built  Like  a  Steel  Bridge 

Lamson  Gravity  Conveyors  are  braced  and  trussed  like  a  steel  bridge  to  withstand  deflection 

or  side-sway  under  load 

rooms,  manufacturing  departments,  and  wherever  products  are  placed 
on  the  conveyor,  and  removed  by  workmen. 

Where  economy  of  space  is  important,  the  conveyor  is  hung  from 
the  ceiling,  out  of  the  way  of  workmen  and  machinery.  Steel  hangers 
and  diagonal  brace  rods  hold  it  rigidly  in  place. 

Portable  Sections 

Our  portable  gravity  conveyors,  mounted  on  swivel  wheels,  are  used 
for  temporary  work,  such  as  loading  and  unloading  cars  and  piling  cases 
in  storage.  Hinged  sections,  which  swing  out  of  the  way  like  a  draw¬ 
bridge  when  not  in  use,  are  installed  across  spaces  which  must  be  kept 
open. 

Curves  and  Switches 

Curves  and  switches  make  our  conveyors  as  flexible  as  a  railroad 
track.  They  run  between  machines,  through  partitions,  around  columns 
and  obstructions  —  they  carry  products  wherever  wanted. 


Carries  Packages  and  Products  Around  Corners 
Lamson  Curves  are  built  in  various  sizes  and  widths  to  care  for  all  kinds  of  loads

From  Truck  to  Washing  Machine 

The  small  picture  shows  the  drivers  unloading  their  trucks  in  the  Empire  State  Dairy, 
Brooklyn.  The  boxes  of  empty  milk  bottles  starting  down  this  chute  pass  along  the  gravity 
spiral,  shown  in  the  large  picture,  and  are  conveyed  by  gravity  direct  to  the  washing  machines 

Lowering  Devices 

For  lowering  packages,  we  build  all  necessary  types  of  chutes  and 
lowering  devices.  A  straight  chute  is  the  simplest  device,  and  is  practi¬ 
cal  where  the  distance  is  short. 


Spiral  Chutes 

To  economize  space,  chutes  between  floors  are  built  in  the  form  of 
a  spiral,  either  open  or  closed.  In  design,  they  are  like  a  spiral  staircase, 
the  stairs  being  replaced  by  the  metal  chute  down  which  the  packages 
slide.  Products  are  placed  on  the  spiral  blade  at  any  desired  floor. 

A  spiral  chute  with  a  number  of  blades  gives  the  same  service  as 
a  number  of  separate  chutes,  without  a  corresponding  increase  in  cost 
or  space  occupied. 

Spiral  Conveyors 

The  gravity  conveyor  is  curved  into  a  spiral  to  provide  a  continuous 
system  for  lowering  packages.  The  great  advantage  of  the  gravity  spiral

is  its  “live”  storage  capacity.  It  makes  no  difference  how  packages  are 
placed  on  the  conveyor,  they  are  stored  on  the  spiral  and  are  instantly 
available  as  wanted  at  the  delivery  point. 

Boosters  and  Elevators 

The  booster  is  a  simple  elevating  section  used  on  a  long  line  of 
conveyor  for  raising  packages  to  a  point  where  gravity  can  operate. 

The  inclined  elevator  is  built  like  the  booster  and  is  used  for  con¬ 
veying  products  between  floors.  Both  the  boosters  and  the  inclined 
elevators  are  built  into  a  conveyor  system  to  receive  and  deliver  packages 
automatically,  without  care  or  attention. 

The  Lamson  Vertical  Elevator  utilizes  constantly  moving  cars  to  raise

are  built  in  short  lengths  to  raise  packages  high  enough  to  be  carried  down  a  long  line  of 
conveyor,  and,  like  the  one  pictured,  they  are  built  to  extend  between  floors

packages.  Like  the  inclined  elevator,  its  action  is  entirely  automatic, 
both  in  loading,  lifting  and  unloading  packages  and  products. 


Other  Types  of  Lamson  Conveyors 

In  addition  to  our  gravity  conveyors,  we  build  many  different  types 
of  Pneumatic,  Belt,  and  Automatic  Conveyors.  With  this  wide  variety 
of  standard  Lamson  Conveying  Apparatus,  we  install  complete  conveying 
systems  to  meet  every  requirement  of  the  industrial  plant,  without  having 
to  design  and  build  costly  special  machinery.

HOW  LAMSON  GRAVITY  CONVEYORS 

ARE  USED 

IAMSON  Gravity  Conveyors  are  used  for  loading,  unloading,  and 
carrying  all  sorts  of  materials  and  products  indoors  and  out. 
.  They  are  used  in  all  kinds  of  industrial  plants  and  business 
^  houses  —  in  stores,  warehouses,  and  factories.  They  are  a  neces¬ 
sity  in  the  receiving  and  shipping  departments.  Incoming  packages  are 
placed  on  the  conveyor  in  the  car  or  truck  and  carried  direct  to  the 
stockrooms  or  departments  where  wanted.  Outgoing  packages  are  con¬ 
veyed  in  the  same  quick  and  economical  way.  There  is  no  time  lost 
trucking  the  products  to  the  platform  elevator,  and  waiting  while  a  car  is 
brought  to  the  right  floor. 

Automatic  scales  weigh  the  packages  as  they  pass  along  the  con¬ 
veyor.  Tare  is  mechanically  computed  — the  operator  reads  the  weights 
as  fast  as  the  packages  pass  over  the  scale  section. 

In  the  retail  store,  packages  in  hampers  are  carried  by  Gravity  and 
Lamson  Inclined  Elevators  from  the  delivery  bins  to  the  street,  where 
they  are  loaded  on  the  delivery  trucks. 


Weighing  Without  Waiting 

These  packages  are  automatically  weighed  as  they  pass  along  the  gravity  conveyor.  This 
view  was  taken  in  the  plant  of  the  Hotaling-Warner  Company,  Syracuse,  New  York

“Gravity”  Out  of  Doors 

Gravity  conveyors  make  great  savings  in  work  out  of  doors  where 
rough  products  are  handled.  On  construction  jobs,  biick,  hollow  tile, 
bags  of  cement  and  sand  on  wooden  pallets,  rolls  of  roofing  paper  and 
other  supplies  are  carried  from  the  wagon,  truck,  or  storage  pile  to 
where  they  are  used. 

In  the  brickyard,  bricks  and  tile  are  conveyed  from  the  kilns  to  the 
cars  or  barges  in  which  they  are  shipped.  In  the  industrial  plant,  pig 
iron  is  conveyed  from  the  cars  to  the  storage  yards,  and  boards,  shooks, 
and  bundles  of  stock  to  the  lumber  piles.  A  few  lengths  of  portable  con¬ 
veyor  which  are  moved  around  the  factory  yard  where  wanted,  simplify 
the  hundred  and  one  odd  jobs  of  moving  materials  and  products. 

On  docks  and  in  freight  houses,  our  conveyors  carry  the  barrels, 
boxes,  crates,  baskets,  and  other  packages  in  and  out  of  the  freight  cars 
and  ships  and  convey  them  about  the  storage  sheds. 


How  the  Department  Store  Speeds  up  Delivery  of  Parcels

carries  them  to  the  street  level  for  delivery.  This  view  shows  part  of  the  delivery  room  in

CONVEYING  BY  GRAVITY 


Conveyors  in  Ware¬ 
houses 

Speed  in  shipping  orders  is 
vitally  important  in  the  ware¬ 
house  and  wholesale  establish¬ 
ment.  Our  conveyors  carry  all 
kinds  of  packages  quickly  and 
cheaply— barrels,  cases  of  shoes, 
rolls  of  paper,  crates  of  fruit, 
boxes  of  dry  goods,  hardware, 
groceries,  drugs,  etc.  They  cut 
out  the  delays  that  come  when 
porters  truck  the  packages  about 
the  building. 


For  Materials  in  Bags 

With  simple  wooden  pallets,  bags  of  cement, 
grain,  and  other  materials  are  carried  by  Lamson 
Gravity  Conveyor 


Inclined  or  vertical  elevators  raise  all 
incoming  packages  to  the  desired  floors, 
where  gravity  conveyors  carry  them  to 
where  they  are  stored.  Portable  convey¬ 
ors,  mounted  on  swivel  wheels,  are  used 
by  the  stock  boys  to  carry  the  packages 
to  the  bins  or  stock  piles. 

The  same  conveyors  carry  outgoing 
packages  to  the  spirals  or  chutes  which 
terminate  in  the  shipping  room.  This 
continuous  conveying  system  keeps  pack¬ 
ages  steadily  on  the  move. 

More  stock  can  be  accommodated  in 
a  given  floor  area,  as  the  porters,  with 
their  cumbersome  trucks,  are  not  required. 

Shipments  are  made  up  immediately 
the  order  comes  in.  Packages  from  the

Conveying  Barrels

cheaply  carried  by  gravity  conveyor

Stock  in  Process  is  Kept 
Down  in  This  Plant 

Tote  boxes  of  finished  work  are 
sent  right  from  the  machine  to 
the  next  job  —  stock  does  not 
accumulate  in  the  aisles,  but  is 
kept  on  the  move 


Red  Hot,  but  Easy  to  Handle 
These  case-hardening  boxes, 
while  still  red  hot,  are  pulled 
from  the  furnace  to  the  gravity 
conveyor,  which  carries  them  to 
the  hardening  tank 


[26] 


CONVEYING  BY  GRAVITY 


From  the  Sand  to  the  Sand  Blast 

In  the  foundry,  castings  as  they  come  from  the  moulds  are  carried  on  pallets  or  in  trays 
to  the  sand-blast  room  or  pickle  room.  The  conveyors  can  be  moved  about  the  foundry 

wherever  they  are  wanted 


stock  piles  or  bins  are  simply  placed  on  the  conveyor,  which  carries 
them  direct  to  the  waiting  trucks  or  freight  cars. 


Increasing  Factory  Production  with  Conveyors 

Lamson  Gravity  Conveyors  increase  factory  production  by  keeping 
the  workmen  always  supplied  with  plenty  of  material.  Parts  and  products 
are  conveyed  between  machines,  departments,  and  buildings.  Materials 
are  not  held  up  on  the  floors  or  at  the  elevators,  but  are  carried  direct 


to  the  next  operation  immediately 
they  are  finished. 

In  the  Foundry  and  Machine 
Shop 

Conveyors  are  valuable  in  machine 
works,  especially  in  plants  such  as 
automobile  factories,  where  large 
production  of  a  uniform  product  is 
daily  turned  out. 


Flasks  are  carried  from  the  storage  yard 
to  the  moulding  floor.  No  more  waiting 
for  the  lumpers  who  are  busy  in  another 
part  of  the  building 


[27] 


CONVEYING  BY  GRAVITY  - 


Saves  a  Five-Minute  Walk 
Materials  for  the  machine  shop 
formerly  had  to  be  carried  from 
the  storage  yard  around  a  wing 
of  the  factory  —  now  they  are 
pushed  through  the  hinged  sash 
in  this  window  and  are  carried 
by  the  conveyor,  shown  in  the 
larger  picture,  direct  to  the  ma¬ 
chines  where  wanted 


In  the  foundry,  output  is  not  dependent  on  the  lumpers  —  flasks  are 
brought  by  conveyor  from  the  storage  to  the  moulding  floor.  Cores  are 
carried  in  the  same  way  from  the  core  ovens  to  the  foundry  floors. 

Iron  pigs  are  conveyed  from  the  cars  to 
the  stock  piles,  and  castings  from  the  foun¬ 
dry  to  the  snagging  and  pickling  rooms. 

In  the  machine  shop,  castings  and  small 
parts  in  tote  boxes  are  conveyed  from  ma¬ 
chine  to  machine.  Maximum  output  is 
obtained  continuously,  as  materials  are  auto¬ 
matically  and  surely  delivered  to  each  work¬ 
man,  with  no  lost  time  between  operations. 


Large  iron  castings  are  carried 
flat  on  the  conveyor  to  and  from 
the  planers  and  milling  machines 


In  the  Assembling  Department 

Conveyors  greatly  speed  up  the  work  of 
the  assembling  departments  in  machine, 
electrical,  and  specialty  manufacturing  plants. 
[28] 


“  Gravity  ”  as  a  Work  Bench 

No  time  is  lost  in  getting  these  Delco  Light  outfits  to  the  shipping  platform.  The  crates 
are  bolted  to  the  skids  as  the  machines  pass  along  the  conveyor.  This  view  was  taken  in  the 
plant  of  the  Domestic  Engineering  Company,  Dayton,  Ohio 


In  the  Food  Products  Plant 

Speed  in  handling  is  essential  in  fac¬ 
tories  where  food  products  are  made, 
particularly  if  perishable  materials  are 
used. 

Conveyors  are  especially  valuable  in 

the  canning  and  preserving  factory,  owing 

to  the  short  working  season  and  the  scare-  These  carburetors  are  conveyed  in 

trays  between  the  machining  and 

ity  of  labor.  Raw  fruits  and  vegetables  assembling  operations 


They  bring  the  necessary  pieces  to  the  workmen  when  wanted.  They 
save  time  and  labor  where  medium-sized  machines  are  crated  for  ship¬ 
ment.  The  machines  are  assembled  on  wooden  skids  and  conveyed 
through  the  shipping  room.  As  they  pass  along  the  conveyor,  the  crates 
are  bolted  to  the  skids  and  the  shipping 
addresses  are  stenciled.  The  crated  ma¬ 
chines  are  then  conveyed  direct  to  the 
waiting  cars  or  delivery  trucks.

Milk  cans  come  from  the  automatic  vertical  ele¬ 
vator  in  a  steady  stream  and  are  carried  to  where 
wanted  by  the  gravity  conveyor 


The  operator  is  shown  placing  a  can  on  the  short 
gravity  loading  section.  The  other  can  has  just 
been  picked  up  by  the  car.  The  action  of  the 
elevator  is  automatic  —  no  time  is  lost  waiting  for 
a  car.  These  views  show  elevator  in  the  New 
Haven  Dairy,  New  Haven,  Conn. 


Where  a  Straight  Rise  is  Desirable 
Lamson  vertical  elevators  occupy  little  space,  but 
convey  a  large  volume  of  work  in  a  steady 
stream.  They  are  automatic  in  loading,  lifting, 
and  unloading 


[30] 


No  More  Interruptions  to  Work  Here 

This  operator  does  not  have  to  leave  his  filling  and  carbonating  machine  to  carry  cases  of 
filled  boxes  to  the  trucks  or  storage.  The  cases  are  filled  right  on  the  conveyor  and  are 
automatically  carried  where  they  should  go.  This  view  shows  part  of  the  plant  of  the 

O.  K.  Bottling  Company,  New  York 


are  conveyed  in  tubs,  baskets, 
or  similar  containers  from  the 
receiving  platform  to  the  manu¬ 
facturing  divisions. 

Conveyors  systematize  the 
work  of  the  packing  room  in  the 
canning  plant  and,  in  fact,  wher¬ 
ever  food  products,  candy,  soap, 
or  units  of  regular  size  and  shape 
are  boxed  for  shipment. 

A  constant  stream  of  boxes 
or  cartons  is  conveyed  past  the 
employees  who  pack  the  goods, 
nail  or  seal  the  boxes,  stencil  and 
weigh  them.  The  boxes  ready 
for  shipment  are  then  conveyed 
to  the  cars,  trucks,  or  storage. 

In  Bottling  Plants 

Gravity  conveyors  assure  con¬

A  Sanitary  Conveyor  for  the  Sanitary  Dairy 
This  view  shows  our  sanitary  gravity  conveyor  in  the  dairy  filling  room.  The  filled  bottles 
are  carried  by  other  conveyors  to  the  refrigerator  and  shipping  platform 


Out  of  the  Way  of  Machinery  and  Workmen 
This  gravity  conveyor  in  the  Harrower  Mills, 
Amsterdam,  N.  Y.,  carries  boxes  of  finished 
product  from  the  packing  room  right  through 
the  mill  to  the  shipping  room 


and  breweries  by  carrying  cans, 
barrels,  and  cases  of  bottles  be¬ 
tween  operations.  In  the  delivery 
department,  they  increase  the 
efficiency  of  the  motor  trucks,  as 
full  packages  are  automatically 
brought  to  the  truck  drivers  imme¬ 
diately  the  empties  are  discharged. 

For  milk  plants  and  dairies, 
we  build  a  special  sanitary  con¬ 
veyor.  The  roller  is  equipped 
with  hermetically  sealed  heads, 
which  prevent  any  milk  or  other 
liquid  from  penetrating  inside. 

In  Shoe  and  Rubber 
Factories 

In  shoe  factories,  raw  leather 
is  conveyed  in  the  receiving  and

lasts  from  the  manufactur¬ 
ing  departments  to  the  last 
storage,  and  cases  of  fin¬ 
ished  shoes  from  storage 
to  the  shipping  room. 
Rubbers,  overshoes,  auto¬ 
mobile  tires,  and  rubber 
goods  of  all  kinds  are  car¬ 
ried  in  suitable  trays  or 
containers  in  the  rubber 
factory. 

In  Wood -Working 
Shops 

In  the  wood-working 
shop,  stock  is  conveyed 
between  the  saw,  planer, 
and  gluing  bench,  and  in 
the  manufacturing  and 
finishing  divisions.  Fin¬ 


ished  work  is  conveyed  in  perfect  safety, 
and  is  not  subject  to  bruising  and  scratch¬ 
ing  through  careless  handling. 

In  Textile  Industries 

In  textile  mills,  trays  of  full  and  empty 
bobbins,  spindles,  and  spools  are  carried 
between  the  roving  and  spinning  rooms 
and  the  weave  sheds.  In  the  cloth  hall 
and  shipping  room,  as  well  as  in  finishing 
companies  and  print  works,  rolls  and 
bolts  of  cloth  are  conveyed  on  simple 
wooden  pallets. 

Cloth  and  finished  goods  are  carried 
in  a  similar  way  in  clothing  factories 
and  knitting  mills. 


Unites  a  Scattered  Plant 
This  gravity  conveyor  carries  rolls  of 
cloth  over  a  bridge  between  two  build¬ 
ings.  It  brings  the  same  manufacturing 
economy  as  if  the  different  operations 
were  performed  in  the  same  building 


For  Conveying  in  the  Factory  Yard 
This  conveyor,  supported  on  wooden  horses,  can  be 
moved  about  wherever  wanted  in  the  yard.  The  pic¬ 
ture  shows  it  carrvine  lumber  from  the  drv  house

to  the  washing  machines  in  the  Bismarck  Gardens,  Chicago,  Ill. 


For  Fragile  Articles 


Safety  in  handling  is  one  of  the  most  important  advantages  of  the 
Lamson  Gravity  Conveyor — the  most  fragile  articles  are  carried  without 
danger  of  breakage.  In  restaurants,  dishes  are  carried  in  trays  to  the 
washing  machines ;  in  glass  works  and  potteries,  bottles,  jars,  and  china- 
ware  articles  are  conveyed  in  the  manufacturing  and  packing  divisions. 
Electric-light  bulbs,  one  of  the  most  fragile  of  glass  products,  are  safely 
conveyed  by  gravity  in  wooden  trays. 


In  Every  Industry 

Production  is  increased 
in  every  industry  through 
the  application  of  our  con¬ 
veyors.  No  matter  what 
the  product  handled  or 
what  the  problem,  Lamson 
Conveyors  will  save  time 
and  expense,  and  enable 
more  work  to  be  done  with 
less  effort. 


Even  electric-light  bulbs  can  be  carried  in  perfect  safety ;
